What Are Fat Burners?

Fat burners are dietary supplements designed to enhance weight loss efforts by increasing fat metabolism, impeding fat absorption, and promoting fat oxidation during exercise.

Fat burners often contain ingredients like caffeine, green tea extract, or capsaicin, which are known for their thermogenic properties—they raise your body’s core temperature, thereby boosting your metabolism and calorie burn rate.

How Do Fat Burners Help With Weight Loss?

Fat burners assist with weight loss by influencing several bodily processes, including thermogenesis, appetite, energy levels, and fat oxidation.

Increased Thermogenesis

Fat burners often contain thermogenic compounds like caffeine and capsaicin, which enhance calorie burn by raising the body’s core temperature. A study in the International Journal of Obesity found that thermogenesis could increase energy expenditure by up to 5%. [3]

Appetite Suppression

Ingredients like glucomannan, which are regularly found in the best fat burners, can help suppress appetite by creating a feeling of fullness, reducing overall caloric intake. A 2008 study in the American Journal of Clinical Nutrition showed participants consuming glucomannan lost more weight compared to a placebo group. [4]

Increased Energy

Caffeine, a common ingredient in fat burners, boosts energy levels, reducing perceived effort during workouts, and leading to longer, more intense exercise sessions. A study in the Journal of Strength and Conditioning Research showed caffeine intake improved workout performance by 11%. [5]

Fat Oxidation

Green tea extract, another common ingredient, promotes fat oxidation, or the body’s ability to break down fat into usable energy. A 2011 study published in Obesity Reviews demonstrated green tea extract significantly increased fat oxidation, especially during exercise. [6]

Types of Fat Burners

Fat burners come in various forms, each targeting different aspects of weight loss, including carb blocking, thermogenesis enhancement, fat blocking, and appetite suppression.

Carb Blockers

These fat burners inhibit the digestion and absorption of carbohydrates by blocking the enzymes needed for their breakdown.

The unabsorbed carbs are then passed out of the body without contributing to calorie intake. For example, white kidney bean extract is a popular ingredient in carb blockers.

Thermogenic Fat Burners

Thermogenics increase your body’s temperature to boost metabolism and calorie burning. Common ingredients of these fat burners include caffeine, green tea extract, and capsaicin from chili peppers.

Fat Blockers

Similar to carb blockers, these fat burners prevent dietary fats from being absorbed in the intestines. Orlistat is an example of a fat blocker that prevents about 25% of the fat you eat from being absorbed.

Appetite Suppressants

As the name suggests, these fat burners control hunger pangs by making you feel fuller or by altering the hormones related to hunger. Glucomannan, a type of dietary fiber, is often used in these supplements due to its water-absorbing properties that create a sense of fullness.

Find the Best Fat Burners in 2024

Choosing the best fat burners requires careful consideration of personal goals, product reviews and ingredients, professional advice, and the preferred form of intake.

Identifying Personal Goals

Understand your weight loss objectives before choosing fat burners. If you want to reduce excessive snacking, an appetite suppressant might be ideal. For those looking to increase workout intensity, a thermogenic fat burner could be beneficial.

Reading Reviews and Researching Ingredients

Reviews can provide insights into the effectiveness of fat burners. However, it’s equally important to research the ingredients. Look for products that contain scientifically-backed ingredients like green tea extract or glucomannan.

Consulting with a Healthcare Professional

A healthcare professional can provide personalized advice based on your health history and current medications. They can help identify any potential risks or interactions and pinpoint the best fat burners for you.

Pick Either Pills or Powders

Fat burners come in different forms, including pills and powders. Pills are convenient and easy to take, whereas powders can be mixed with drinks and may be easier for those who have difficulty swallowing pills. Your choice depends on personal preference and lifestyle.

Common Ingredients in the Best Fat Burners

The efficacy of fat burners often lies in their ingredients, each offering unique metabolic benefits that contribute to weight loss.


A potent stimulant, caffeine boosts metabolism and increases energy expenditure. It’s also known to enhance athletic performance, making workouts more effective.


Derived from the root of the konjac plant, glucomannan is a fiber that expands in the stomach, promoting feelings of fullness and reducing caloric intake.


This amino acid plays a pivotal role in fat metabolism by transporting fatty acids into the mitochondria for energy production, supporting weight loss and exercise performance.

Green Coffee Bean Extract

Rich in chlorogenic acid, green coffee bean extract slows down the absorption of carbs and aids in fat metabolism. It’s found in many of the best fat burners.

Cayenne Pepper Extract

Capsaicin, the active compound in cayenne pepper, has thermogenic properties that increase calorie burn and stimulate fat oxidation.

Conjugated Linoleic Acid

Commonly found in dairy and beef, Conjugated Linoleic Acid (CLA) reduces body fat by inhibiting the enzyme that stores fat and aiding in fat breakdown.

Green Tea Extract

Packed with antioxidants called catechins, green tea extract stimulates fat oxidation and boosts metabolism, especially when combined with caffeine.

Beyond supplement fat burners, various natural and sustainable methods can be utilized for burning fat, including rigorous workout regimens, dietary adjustments, mental well-being practices, and mindful eating habits.

High-Intensity Interval Training (HIIT)

High-Intensity Interval Training, often abbreviated as HIIT, involves short bursts of intense exercise alternated with low-intensity recovery periods.

It’s particularly effective at burning fat because it increases your metabolic rate for hours after exercise, leading to more calories burned throughout the day.

Healthy Diet

A balanced diet rich in lean proteins, whole grains, fruits, and vegetables can help boost your metabolism and reduce body fat. These foods are high in fiber and protein, which are essential for weight management.

For instance, lean meats like chicken breast are low in fat and high in protein, which requires more energy to digest than fats or carbohydrates, thus burning more calories.

Stress Management

Chronic stress can lead to hormonal imbalances that cause weight gain or hinder weight loss, even when using the best fat burners.

Techniques like yoga, meditation, and deep-breathing exercises can help manage stress levels, contributing to a healthier metabolic rate and improved fat loss.

Portion Control

Eating too much of any food, healthy or not, can lead to weight gain. Portion control is about understanding how much a serving size of food is and how many calories or how much food energy a serving contains.

By controlling portions, you can avoid overeating while still enjoying your favorite foods, leading to sustainable weight loss and fat burn.
